DAVID HERBERT WINSLOW, OF RALEIGH, NORTH CAROLINA.

ROAD-SCRAPER.

Application filed January 14, 1919.

To @ZZ whom t may concern:

Be it known that I, DAVID HERBERT VINs- Low, a citizen of the UnitedStates, residing at Raleigh, in the county of Wake and State of NorthCarolina, have invented a new and usef-ul Road-Scraper, 0f which thefollowing is' a specification.

This invention relates to a machine for use in repairing roads, one of|the objects of the invention being to provide a simple, inexpensive andeiiicient structure which, when drawn Over a road, will remove ridgesVand other raised port-ions by first loosening the surface material andthen scraping it into depressions after which, as a partl of the oneoperation, the material thus distributed is packed so as to leave theroad smooth and free from all undesirable depressions and raisedportions.

A still further object is to provide a machine of this character whichwill operate efficiently on Iall kinds of rural roads Iwhether they beof ordinary soil, of sandclay, gravel or macadam.

Another object is to provide a road machine of this charac-ter which canbe repaired easily, and which can be readily manipulated, ythe saidmachine operating in the same manner as a plane to loosen and shave olfelevated portions and lill in the depressions.

lVith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention consists of certain novel de'tailsof construction -a-nd combinations o-f parts which will be hereinaftermore fully described and pointed out in the claim it being lunderstood"that various changes may be made in the construction and arrangement ofthe parts without departing from the spirit, or sacricing any of theadvantages of the invention as set forth in the appending claim.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings:

2 an intermediate cross beam and 3 a rear cross beam, all of these beamsbeing connected at their ends by longitudinal side beams l to rthe frontends of which are connected the ends of a chain 5 to which the draftanimal or a tractor may be connected.

Spikes 6 which are preferably case hardened are driven through the beamsl and 2 and are arranged in longitudinal series. The points of thesespikes extend below the beams l and 2 so as 'to dig into the surface ofthe road and loosen the material thereof. A scraping blade 7 is securedto and covers the front face of the rear beam 3. Arranged back of thebeam 3 is a packing section formed of side strips S to the bottom facesof which are secured 'the ends of packing strips 9 which are inclinedupwardly and forwardly and arranged in lapped relation as shownin Fig.2. Chains l() or the like connect the rear ends of beams 4 to the fron-tends of the strips 8.

In using the device herein described it is placed on the surface of theroad "and drawn forward by any means desired. The points of the spikes 6will dig into the surface of the road so as t0 loosen the material. Theblade 7 following these spikes will act as a. slicer and scraper,engaging the loosened `material and scraping away the ridges or raisedportions. The material lthus scraped will be drawn along and depositedin the depressions in the surface of the road. The packing sectio-nfollowing the blade 7 will ride over the material thus distributed andwill pack it tightly, leaving a smooth road surface free of allundesirable depressions and raised portions. If desired any suitableweight may be placed 0n the packing section.

What is claimed is:

A road scraper including beams, spikes carried by the beams `andprojecting therebelow for loosening the surface material of a road,another beam back of the spike carrying beams, a scraping blade upon thefront facev thereof, connections between the beams, all of said beamsbeing extended transversely of their path of movement and cooperating tolimit the downward movement of the spikes into the surface material ofIn testimony that I claim the foregoing the road, connected packingstrips back olf as my own, I have hereto affixed my signathe 'beams andarranged in lapped relation, ture 1n the presence of two witnesses.

said strips being inclined upwardly and or- DAVID HERBERT WINSLOW.warclly and'movable'laterally and. vertically Witnesses: relative to theloeams, and flexible connee- W. S. FALLIS, tions lbetween said stripsand 'the beans. GEO. F. Smm.
